School me on spring options.

Got my springs in, finally. I would hate to have been someone who had to wait from them from the initial order. I ordered back in early sept and was told it would be 2 weeks untill they shipped. I finally got the springs last week.

 

So springs opinions. The military wrap is not super tight, but I suppose it will do what it is supposed to. Springs are beefy and heavy. They are not painted, just "oil rubbed". I will likely remove the overload springs, clean everything with degreaser, and paint black. The center pin is not very tight and the overload springs will spin on the main springs. The centering pin nut looks like someone smashed it with a rock to get it get to length. I'll remove it when I paint it, and then put it back together with a castellated lock nut, tack it in place and then round it out. To fit my spring perch kit the nut will need to be rounded off.

 

Overall not bad, took a long time and was comparatively expensive for lacking in a few things like paint, decently tight centering pin, and a center pin nut that doesn't look like it was chiseled off with 1957 Cadillac bumper.

The center pin is peened over during manufacturing to prevent the nut from falling off.

 

The U-bolts will compress the pack so there is no movement of the overload leaf.

 

Your springs are fine. Paint them if you want.

Sam's just being Sam.  :laugh:  The center pin does leave something to be desired on these springs aesthetically, but it didn't worry me because once they are installed it's useless anyhow. It's just to hold the leafs together until you torque them down with the u-bolts.

 

I installed these MT springs on my MJ over ten years ago, and initially they gave me nearly 3" of lift over what it was with the original sagged springs that I had. In about a year they settled down about an inch. Didn't paint them either, and they still look new.

 

You can install an aftermarket u-bolt clamp aft of the main axle u-bolts like I did if you're worried the leafs will move, but it's really not necessary. It's just an ornament.   :wink:

I'm in this same boat now and happy I found this thread. I want to verify because I'm a little lost here... did GS make you a lifted MT spring or did you purchase the stock height MT spring?

 

Thanks.

 

They offered a lift spring that was not on their website in the heavy duty (MT) weight rating. When I called they said they had an order in for several sets and it would be delivered to them from the manufacturer in 2 weeks. He made it sound like the initial order or group buy for the other couple of dozen had been in process for something like 12 weeks.

 

Makes it sound like long lead time for the lift option.

Thats cool for you. As I posted above I was counting in weeks not days. Not sure how you got free shipping but it was $70 for my pair. Do tell your secrets!

It's 20" from the center of the wheel cap to the bottom of the flare Sam. And that's with using longer than stock (about 1") Teraflex extended shackles. I had to add these to get the rear end back up as the MT springs compressed and settled down an inch during the first year.

Don, what is your current measurement on your front end, and what is the stock measurement? I prefer little to no rake which is how your truck appears to me.

I was going to order a set of Alcan's but I'm impatient. sdtrucksprings was a pain to order from online, so I tried general spring. had a tracking number 20 mins later and they arrive friday. I'll be going with a linear custom valved shock in hopes of improving ride hopefully I'll be satisfied and not have to get a more terrain specific setup

Right now up front Wahoo I'm 33" from the floor, through the center of the wheel hub to the bottom of the flare. The only parts that are giving me lift up front are the OME 930 springs (NLA, replaced by OME 2930), and fresh Mopar spring pads. I'm about 2-1/2" over stock.

 

The rear has GS MT springs with Teraflex 1974100 shackles. Measuring the same way as the front come to 34", so yeah, very little rake.

I'm going to point out that the center pin doesn't just keep the pack together until you clamp down the ubolts.  It's needed after then too, as it is the only thing that positively locates the springs together in the pack, and into both the spring perch and the top plate.  I wouldn't install a spring pack with a loose pin, it is asking for it to fail at some point, although I think it's unlikely to ever be an issue.

 

Any decent auto parts store can get them.

This.  Putting together my CJ, I bought center pins with larger heads, and carefully ground them down to a perfect fit in the spring pad to ensure there was no room for movement.  A center pin that is undersize compared to the hole in the spring pad will allow some movement even with the u-bolts torqued.

I'm going to point out that the center pins on my MT springs were tight. I said it looked like crap because as Sam said, the bolt was cut off with a crusty bolt cutter or something and looked like crap. But I didn't see that as any reason to replace it. And if and when I ever take them off and they start to separate because the center pin has failed somehow, I have plenty of C-clamps.

 

Did anyone else have any center pin problems on your General Spring MJ MT springs?

My heads were too big. I took the bolt/pin out and spun it on a belt sander for a couple of seconds.............solved. 

 

Nothing happens when you take the pin out, no need for clamps. 

 

It does just what it's supposed to, center/align the pack, nothing more.

Mine look to have been cut off with bolt cutters also, haven't checked if they are tight.  Haven't installed them yet.

Oh and I found the bushing wasn't fully/correctly pressed into one of the springs. So one bushing sticks out too far to the right, and the other sticks out too far to the left.

 

I'd say the combined tolerance stackup is approaching 3/4". Grrrrrrr. Guess I'll give the balljoint press a try to center them.

I purchased from GS awhile back and can't complain. Got the MT with an extra inch arch and military wrapped. Paired with some OME shocks and just put on some Iron Man 4x4 Fab adjustable shackles. Back rides better than the front now. Got just under 2 inches of lift from factory height with just the springs.
